I'm using BCM20737S SIP module, I want to know that does this module support RTS/CTS flow control?

I had read all over the datasheet of BCM20736S, I just find GPIO:P3 as puart CTS, but RTS is missing.

Hi Kai,

Unfortunately, flow control is not available via the PUART on the module.  This is why the RTS pin no longer appears as a GPIO option in the module datasheet. However, the feature is still available on the SoC.

This is because P1 (Referenced in the WICED™ Smart Hardware Interfaces document) is tied internally to the WP function of the internal EEPROM, so flow control is not available on the module.

Good thread on the subject here: Need clarification on PUART RTS/CTS flow control support
